Raspberry Pi 500+ Detailed Analysis: Enhanced Keyboard PC Review Meta description: Raspberry Pi's latest 500+ model offers a mechanical keyboard and 16GB of RAM in a keyboard computer form factor. Here's what's new and who it makes sense for. Introduction Raspberry Pi has unveiled an upgraded version of its keyboard-built-in computer product - the Raspberry Pi 500+. This model represents a more serious and powerful take on the concept of the Pi 500 intended for people looking for a genuinely practical daily driver computer as an alternative to using Raspberry Pis as hobbyist boards in enclosed enclosures. What the Raspberry Pi 500+ Actually Is Like its predecessors (the Pi 400 and Pi 500) the 500+ is a full computer built into a keyboard - you simply attach a monitor, mouse and power supply to make a fully formed, compact desktop computer. What's New Compared to the Pi 500 The 500+ offers three main upgrades over the standard Pi 500: 16GB of RAM (compared to 8GB in the ...

Edge AI on Microcontrollers - What This Means for Makers in 2026 Meta description: AI is coming to microcontrollers, not just the cloud. See what this means for Arduino, ESP32, and Raspberry Pi makers in 2026. Introduction If you've been following embedded development for more than three years, you have an intuitive grasp of the long-standing paradigm of AI: you send data to the cloud and receive (usually much slower) data back from the cloud. What most makers don't realize is that this paradigm is set to change in 2026. The new crop of microcontrollers in various development boards are being engineered to actually perform AI functions on-device, and this has huge potential for both hobbyists and industrial applications alike. In short, this will let you do interesting edge AI/ML/TinyML things without having to purchase and maintain a server or even a Raspberry Pi - at least not right away. This article will discuss what this means for makers and hobbyists and how it impacts th...

Edge AI on Microcontrollers: Why This is the Next Big Thing in Embedded Hardware Meta description: AI is coming to microcontrollers, not just the cloud: here's what this means for Arduino, ESP32 and Raspberry Pi developers in 2026 Introduction When people think about AI, they often imagine sending information to a server for processing. This will continue to be an option, but an important change is taking place in 2026: major semiconductor manufacturers are starting to produce microcontrollers with specialized processing units for AI algorithms. These microcontrollers have a significant impact on the development of embedded systems, both in an industrial context and in the sphere of personal electronics. What This Actually Means The ability to run AI algorithms on microcontrollers means that in the past, to run such algorithms, one had to have at least a Raspberry Pi, but preferably an industrial computer or an entire cloud server. Microcontrollers such as Arduino or even ESP32 wer...

Arduino Servo Motor Control (Code & Circuit Diagram Included) Meta description: How to control a servo motor using Arduino, including code and circuit diagram. Complete guide with code and troubleshoot tips included. Introduction Servo motors are one of the most versatile types of motor used in robotics- they can rotate to a specific angle and hold that position. This tutorial shows how to wire and control a standard servo motor using an Arduino Uno. What you'll build In this tutorial you'll learn how to connect and control a standard SG90 servo motor. We'll show you how to make a simple program in Arduino to sweep it continuously back and forth, and how to manually control the angle using a potentiometer. This is a great beginner project that introduces robotics concepts and is useful for many robotics applications, such as automated doors, camera gimbals, robotic joints, etc. Parts needed • Arduino Uno development board (any type will do) • SG90 Micro Servo Motor (gen...

How to Set Out Pi Hole on Raspberry Pi Introduction One of the most popular raspberry pi projects, Pi-hole blocks ads and trackers for all of the devices on your network Overview The Pi-hole blocks ads and trackers from devices connected to your network by acting as a sinkhole for the Domain Name System, or DNS. This is a critically important service that enables the conversion of domain names to IP addresses and is used by all computing devices connected to the internet. Requirements Things you will need to set this project up include: • Raspberry Pi (any model with network connectivity should work, Pi 3, 4, and 5 all work well, and are popular choices for this project, even Pi Zero W works for a home network) • Micro sd card (At least 16 GB is needed, but can be anything beyond that) with raspberry pi os                   installed • Power supply for your raspberry pi • Network connection (Ethernet cable is recommended) Features • Bloc...

Arduino Vs ESP32 Vs Raspberry Pi: Which one should you choose? Review Meta description: Confused about the differences between Arduino, ESP32 and Raspberry Pi? In this blog, we compare the key differences, use cases, and which one to buy. Introduction If you are new to the world of electronics and IoT, you might be faced with the dilemma which is Arduino, ESP32, or Raspberry Pi? All of these are completely different things, despite the fact that they are often used together, but not at the same time. In this blog, we will review what are the main differences between these platforms and which one is better for your electronics project. The short answer is: Arduino – is great for simple and straight forward electronics projects (sensors, relays, etc.) which do not require Wi-Fi or any other advanced features; ESP32 – is Wi-Fi-enabled microcontroller, best for IoT projects; Raspberry Pi – is a full-scale computer, capable of running complex tasks and applications. Overview of Arduino, ESP...
